Travel Insurance Deductible Tradeoff Calculator

Compare two travel insurance deductible choices by combining the premium you pay with the expected out-of-pocket amount if a covered loss occurs. The calculator estimates the annualized or trip-period cost of each option using your own claim probability and typical covered loss amount.

It is useful when two policies offer similar benefits but trade a lower deductible for a higher premium. The result highlights which option has the lower expected cost under the assumptions you enter, while keeping in mind that actual claims can be much higher or lower than an average estimate.

1. Enter both deductibles
Use the amount you would pay before the policy responds to a comparable covered loss.

2. Enter the matching premiums
Keep both premiums on the same time basis, such as per trip or per policy year.

3. Estimate claim probability
Use your own best estimate for the chance of at least one comparable covered claim during that same period.

4. Enter a representative covered loss
Use a loss amount before the deductible. A value below a deductible reduces the practical difference between the options.

5. Review expected cost and break-even probability
The lower expected-cost option is highlighted, and the break-even probability shows where the cost preference changes.

Expected cost = Premium + Claim probability × min(Deductible, Covered loss) Break-even probability = Premium savings ÷ Additional retained loss

The model assumes one representative covered loss for the comparison period and applies the deductible once. Claim probability is entered as a percentage and converted to a decimal. Actual policies can apply deductibles differently by claim, event, person, or coverage section.

What the result means

The displayed advantage is the absolute difference between the two modeled expected costs, not a guaranteed saving.

Use policy documents and insurer quotations for actual terms; this calculator only compares the inputs you provide.

Given: A traveler compares a $120 deductible plan costing $185 with a $500 deductible plan costing $130. They estimate an 18% chance of a covered loss averaging $1,800 during the insured period.

Calculation:
Lower-deductible expected cost = 185 + 0.18 × 120 = $206.60
Higher-deductible expected cost = 130 + 0.18 × 500 = $220.00
Break-even probability = (185 − 130) ÷ (500 − 120) = 14.47%

Result: The option with the lower expected cost is cheaper under these assumptions by $13.40 for the modeled period.

What does the break-even probability mean?

It is the claim probability at which the two options have the same modeled expected cost. Below or above that point, the premium savings or deductible difference becomes more influential.

Should I use the policy limit as the loss amount?

Usually no. Enter a representative covered loss you want to compare, not automatically the maximum possible policy limit.

What if the loss is smaller than the deductible?

The calculator caps retained loss at the entered loss amount. That prevents it from assuming you would pay a deductible larger than the loss itself.

Does a lower expected cost always mean the better policy?

No. Cash-flow tolerance, exclusions, limits, sublimits, claim handling, and the size of severe losses can matter more than the average-cost estimate.

Can I compare premiums quoted on different time periods?

Convert them to the same period before entering them. The probability estimate must use that same period as well.
